Abstract

Cognitive psychology studies phenomena that cannot be directly
observed. Scientific knowledge about the brain is extensive, but there is still a
lot to be understood about its functions. Cognitive functions are weakened in
dyslexic children; this is reflected in highly individual problems regarding the
reading skills. Reading is a process which consists of decrypting graphic
characters (perceptual level) and understanding the meaning of words (cognitive
level). These levels cannot be separated. An approach – fuzzy logic –
is used in order to address this issue and create a model of the dyslexic user,
based on which technologies can be individually tailored to a particular
dyslexic. We discusse the possibilities of the use of the mathematical apparatus
for the categorisation of users with regard to their "black box". Further, we
focuse on the development of new assistive technologies targeted at specific
attention disorders, reading disorders, as well as information processing
disorders.
